Abstract
The prototype of a production can be manufactured directly from its 3D CAD model data by using rapid prototyping technology, and can be renewed conveniently after modifying the CAD model. In this paper, the basic principle, typical prototyping systems are introduced, and rapid prototyping methods such as selected laser sintering of powder material, fused deposition modeling of threadlike material and laminated object manufacturing are presented. An application of rapid prototyping technology on design and development of first aid kit is described in detail. It is indicated that rapid prototyping technology is an effective means to lower the cost and shorten the period of development of medical equipment.
